A 25.00-mL sample of an unknown H2SO4 solution is titrated with a 0.1000 M KOH solution. The equivalence point is reached when 22.42 mL of KOH solution is added.
a) Write a balanced chemical reaction:
b) Identify the reaction as precipitation, acid-base, oxidation-reduction and/or gas forming.
c) What is the concentration of the unknown solution?
It is possible to determine the ionization energy for hydrogen using the Bohr equation. Calculate the ionization energy for an atom of hydrogen, making the assumption that ionization is the transition from n=1 to n=∞.
Exactly 5.00 days later, the rate of decay was found to be 177 disintegrations per minute. Calculate the half-life, in days, for the decay of this sample.
a 75.0 ml sample of .0500M HCN is titrated with .500 M NaOH. what is the concentration of H+ in the solution after 3.0 ml of .500 M NaOH has been added
A student determines the amount of tetrachlorethylene in a contaminated well water using a purge and trap technique. The student takes 150.0 mL of the well water, spikes the well water with 100 microlitres of 50 ng carbon tetrachloride/mL and purg..
Which metal is associated with the synthesis of cyclopropanes?
we need to form a cyclohexanone with a methyl group at the 6 position and a 2,3-butanediol group (with both OH groups at the back (dashed lines)) at the 2 position. All carbons on the target need to come from the starting materials, but other than..
Four aldehydes and four hydrazines were used to explore hydrazone antibacterial activity in a combinatorial technique. How many reactions and antibiotic screenings would have been required to carry out this analysis in a non-combinatorial fashion?
For each of the following slightly soluble salts, write the equilibrium equation for dissociation and the solubility product expression: a)CuS b)Ag2SO4 c)Zn(OH)2
A total of 0.160 g of this subunit was dissolved in enough water to produce 2.00 mL of solution. At 28 C the osmotic pressure produced by the solution was 0.138atm. What is the molar mass of the protein?
You are performing site-directed mutagenesis to test predictions about which residues are essential for a protein's function. Which of each pair of amino acid substitutions listed below would you expect to disrupt protein function the most
Calculate the molar mass of maltose (which is not an ionic compound). (b) The density of the solution is 1.014 g/mL. Calculate the osmotic pressure of the solution.
Assuming that equilibrium has been reached, calculate Kc and Kp for the reaction.
